    摘要： A method of manufacturing a superconducting wire is carried out by first preparing a material being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7. This material is melted in a platinum crucible. A melt thus obtained is drawn out from a hole provided on the bottom wall of the crucible to be linearly discharged. The linearly discharged melt is cooled and solidified. A cooling/solidifying space for such a step is set at a temperature less by about 10.degree. C. than the solidifying point of the material, and a slow-cooling zone is provided next to the cooling/solidifying space. This slow-cooling zone is provided to be at a relatively high temperature in a portion closer to the hole while having a temperature gradient along a direction for linearly discharging the melt. A superconducting wire being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7 is obtained. This superconducting wire superconducts at 85K.

    摘要： A method of manufacturing an improved conductor wire, especially for use as wiring in audio/video devices is disclosed. The conductor consists of copper having a high purity of at least 99.9 wt. %. High purity copper starting material is formed as a rod which is then heat treated at a temperature in the range of 400.degree. C. to 700.degree. C. for 1 minute to 24 hours. The heat treated rod is then cold worked with a reduction in area of at least 65%. This method provides an electrical conductor wire which avoids irregularities of electron density and thereby eliminates phase differences in a high frequency signal, such as an audio or video signal, passing through the wire to obtain clear transmission and reproduction of an audio sound or video image. The method of the invention increases the residual resistance ratio of the conductor wire to at least 179 or by at least 20% as compared to a conventional conductor which is not heat treated according to the invention. Finally, in a quality control method, the expected audio and video transmission characteristics of a manufactured conductor wire can be evaluated by determining the residual resistance ratio of the conductor wire.
